/**
* Display a list of document records. The data can be out of the history
* manager or from an index query, both abstracted as a DocSequence.
* Sorting and filtering are applied by stacking Sort/Filter DocSequences.
* This is nice because history and index result are handled the same, but
* not nice because we can't use the sort/filter capabilities in the index
* engine, and do it instead on the index output, which duplicates code and
* may be sometimes slower.
